Deep Veins, superficial veins, and perforating-communicating veins are three components of the leg’s venous system that depend on each other. A dysfunction in any of these components can affect the other two. Varicose veins appear when superficial leg veins are place under high pressure which then make them dilate and enlarge. Varicose veins can be a result of: 1) Obstruction, 2) valve incompetence, 3) arteriovenous anastamosis, 4) hereditary, 5) aging

Telangiectasia:

Telangiectasia is known more commonly by most people as spider veins, however there are 4 types of telangiectasia: 1) Simple, 2) Spider veins, 3) Papular, 4) Arborized. Telangiectasia is strictly defined as superficial vessels of the skin visible to the human eye. Telangiectasia can arise from both arterials and veins. There is a wide range of causes for telangiectasia: 1) hereditary, 2) activation of certain hormones and chemicals 3) pressure exerted by crossing legs, 4) tissue loss. These are only a few causes of these little leg veins.
